Boyfriend of swimsuit designer Sylvie Cachay 'would demand porn sex off her and made death threats to kill her before she was strangled and drowned in NYC hotel'

The boyfriend of the swimsuit designer who was found strangled and drowned in a Manhattan hotel would constantly demand porn sex and had made threats to kill her before, a court heard yesterday.

Nicholas Brooks is on trial in Manhattan Supreme Court accused of the murder of Sylvie Cachay who was found on December 9, 2010, in an overflowing bathtub in a room in trendy Meatpacking hotel Soho House in New York.

One of her best friends testified yesterday that Sylvie would complain about him constantly, called him a 'man boy' and said he would get so enraged during their arguments that he would erupt into death threats.

Her pleas: Brooks, pictured here at his 2010

Cachay's 5-page list included 'get a job,' 'wake up by 10,' and 'get
out of bed.'

'She told me that he would get so angry that he would threaten to kill her,' Sharon Lombardo told the court.'She complained about him always being at her house and never leaving.
She complained about him getting stoned all the time.

'She complained
about having to pay for everything. She complained about how angry he
got when he was drinking.She told me he wanted to have sex all the time, like a f***ing rabbit — that’s her words.'

When asked by the prosecutor what her understanding of porn sex was she replied:'That he wanted to have sex all the time, like all the time to the point where it was extremely exhausting for her.'

She also said Sylvie would refer to Brooks as a 'man boy'.

Yesterday jurors were shown pictures of the hotel room where Brooks allegedly strangled and drowned her.

Sylvie's parents Sylvia and Antonio
looked away as close ups were shown of their daughter's face as she lay
in the room with tubes taped to her blueish lips and red marks on her
neck where she had allegedly been strangled, the New York Post reports.

Prosecutors also had to call police yesterday after Brooks' sister allegedly snarled 'awful bitch' at Sharon Lombardo after she testified.
